' My invention relates to improvements in cable car hauls and has for one object to provide a new and improved cable hauling method and system for freight cars and the like such as may be used in 'connection'with car unloaders where successive cars must be moved forward and spotted in a position 7 wherethey are to be loaded or unloaded or otherwise treated.

One object of my invention is to provide a cable car haul apparatus and process wherein a reciprocating cable may be used to feed cars forward and wherein there are two limbs to the cable so that cars on one of the pair of parallel tracks may be fed forward and wherein thereafter the cars on the second of the parallel pair of tracks may be fed forward, making it unnecessary to wait for the return movement of the cable.

Other objects of my invention will appear from time to time throughout the specification and claims.

My invention is illustrated more or less diagrammatically in the v accompanying drawings wherein Figure 1 is a plan view of a layout for cars and cable illustrating my invention; Figure 2 is a detail of the car and cable connection; I .Figure 3 is a detail of the take-up;

A is a car dumper having a car track A extending therethrough, but my invention maybe usedwith-a rotary or other types car dumper wherein the car is turned entirely over to dump its contents to .a level lower than the track and it may be used for moving cars to or from a given point. A is the discharge track extending from the dumper or point to which cars are moved to or from. A is a single approach track along which cars may come on the way to the dumper. A is a switch communicating at one end with the approach track A and at the other with the storage tracks A A preferably arranged in parallel. A A indicate trains of cars located on the storage tracks A A which cars are to be moved.

B and B are cables associated with a drum B about which the cables are wound and a motor 13 drives the drum, there being electric or other suitable controlling means, not here illustrated in detail, to control the operation of the motor. The cable B extends from the drum along the track A to a sheave B, thence across beneath the tracks A and A to a sheave B thence back along the track A past the car dumper or working station and along the tracks A and A to a sheave B, thence back to a sheave B and thence back to the drum. Thus the cable has two separate parallel arms or branches, one extending from the engine to the sheave B, the other extending from the sheave B to the sheave B Attached to the cables B and B are two separate car haul anchorages O, O These car haul anchorages are positioned 011 the cables and so arranged that they do not pass around the sheaves, there being an anchorage for serving each track. It will be noted that their positions on the cables are such that when the anchorage O is at one end of its excursion, the anchorage O is at the other end of its excursion, near the sheave B and vice versa. Associated with these car haul anchorages O, O are cables O there being two for each anchorage, so that the anchorage may be attached at each end, or at two ends or a single point of any one of the cars. As illustrated the cables O associated with the anchorage O are attached to a car Well up the track.

Ordinarily all the cars ahead of the one to which the anchorage O is attached are coupled together, the car immediately following the anchored car is uncoupled and all the remaining cars are coupled together so that when anchorage O is later attached to the first car of the second half, all the remaining cars are moved forward to where the anchorage O can be attached to the last car. The first half of the cars on the track 5 are handled by anchorage O in the same manner described for. anchorage C. When the first half of cars on tracks A and A have been delivered to track A anchorage C is at or near the first of the second half of cars on track 6,. so it may by a slight further travel up the track be attached to the first of the tracks A and A, up track A when anchorage fonto At.

When G has'de: livered the last car onto A, anchorage G is at or-near the last car. on track A readyfor'attachingand feeding the remaining cars to A Ordinarily there are a'few less cars serviced from track A than from A due to the switch.

The haul may be made suffic'iently strong to move all jthe cars on a track at one time when they are coupled together, by attaching anchorage C tothe middle car,all those preceding it are moved on track A to a point opposite junction of tracks A and A when half of'the cars isuncouahead of it inclu'ding the middle ear or carattachment is delivered onto to attac'h'to the middle car ontrackhr and until. the rear of the car to which anchorage is attached, reaches junction oftracks A and A when the rear half of the cars is uncoupled and the balance of the cars are moved onto A the {meantime C has moved same amount and by further movement, equal In up the track the to, the distance between junctionof tracks and lif and junction ofswitch A to track A up'track A anchorage may be attached torear car and move it and the preceding cars forward as desired.

The head IE will not pass through the eye E Since the tension on the cable is exerted along an axis or line parallel with the line of movement of the car, there is no tendency for the withdrawal of'the pin E which is cramped against the sid'es of the aperture into which it is inserted. This method of attachment has the advantage of simplicity and uickness, asthe pin may be inserted or with rawn almost instantaneously.

The use and operation of my invention are as follows:

Maximum efiiciency in moving cars can be attained only-when served with an eflicient car haul and when the labor costs are reduced to a minimum. It is also necessary to be able to reach with the car haul a maximum number of loaded cars with a minimuinde lay and without the use of switching service. As a matter'of fact it is preferable to have a storage system with a .car haul so that the haul itself mayfe'ed to the dumper or unloader at least a half days supplygofcars without requiring a switch engine to provide an additional supply of cars.- I 1 This purpose isaccomplished' by means of 'a car haul system, consistingof a reversible single drum, which drum isscored so that pulling'th'elast car 0 v the unloader after it has been emptied of its load. From this point it is deflected beneath the track and then-back to the drum.

' This gives a cable with two-branches, one

moving in opposition to the other; Asap ranged with the two parallel cartracksthere is one branch ofthe cableassociated with each pair ofrails; When one cable is coming forward and may be usedto feed cars to the'unloader, the other cable will'be going back idle; Figure 2 showsoneform ofiattachme'n't with two-short cables fastened to each anchorage. I

. The adjusting clamp D as shown-makes it possible to change the length of these-cables so thatthe pair'offcabl'esmay bee-fastened to 'a singl'e car' and' may 'b'e used'to- -move it forward or back as thecase-may be. The long screw take-up 13 is necessary totake up slack in the hauling cable.

The electric controller G for the car haul, maybe located at the car unloader 'operators platform and maybe similar "to an ordinary street car controller with contacts G and the manually operablearm' The helper attaches the anchorage tothe car-spreviously described The attachments when not fas-- ill) tened to cars are free to drag along the ground. The operator moves the controller to cause the drum B to reel in on the attached cable, and the entire train of cars ahead of the anchorage moves forward until a loaded car is spotted on the unloader. The operators helper uncouples this car from the others and the operator, by reversing the controller, pulls the remaining cars back to a point clear of the unloader. The car is then unloaded or otherwise treated and the o erator works his controller to move another car onto track A, pushing the empt car off. This continues until the last car in t e string has been placed. By this time the other cable anchorage has been moved back to the other end of its excursion. The helper attaches it to a car, and the process is reversed, by causing the cables to move in the opposite direction, to feed cars from the second track onto track A.

By this arrangement and by keeping all the cars on each track coupled in train, it is possible for the car haul to feed a maximum number to track A with minimum delay, la-

bor and manipulation, because when one anchorage of the car haul reaches track A, the other anchorage is at or near the far limit of its movement, ready to be attached to a car.

In many of the claims I refer to the process of feeding cars as associated with a car unloader and refer to the unloader in the body of the claim. Obviously this is done for convenience only and in order to make clear what I am doing and how the process is carried on. The car haul and the process of operating and using it can, of course, equally well be used for moving cars for any purpose and I want it understood that where I refer to a car unloader or car dumper I use it merely as exemplifying both in specification and claims any device where cars are successively moved and spotted.

I claim:

1. The process of feeding cars to car unloaders and the like, which consists in coupling a series of cars in trains on parallel lines, then selecting a car in one train and propelling it toward the unloader to push the cars ahead until the leading car in the train is spotted on the unloader then uncoupling the leading car, then propelling the selected car backward to move the train back to clear the unloader, then after the spotted car has been unloaded, propelling the selected car forward to push the empty car off the unloader and spot the next car in the train thereon and continuing the process until the selected car has reached the forward limit of its excursion, then selecting a similar car in the other train and repeating the process with i 2. The process of feeding cars to car unloaders and the like which consists in assembling a series of cars coupled in'train, then selecting an intermediate car in the train and applying power to thatcar to propel ittoward the unloader and push the cars in front and pull the ears behindit in the train until theleading car in the train is spotted on the unloader, then uncoupling such leading car and applyingpower to the selected car to reverse the train to clear the unloader, then after the car on the unloader-has been unloaded, applying power to the selected car to move the entire train forwardly, push the empty car off the unloader and spot another car thereon, thenwithdrawing the train to clear andcontinuing the process until the selected car has reached the forward limit of its excursion.

3. The process offeeding cars to ear unloaders and' the like, which consists in providinga seriesof cars coupled in trains in parallel lines, then selecting an intermediate car in one train and propelling it toward the unloader to push the cars in front and to pull the cars behind it until the leading car in the train is spotted on the unloader, then reversing the selected car to move the train back to clear the unloader, then'after the spotted car has been unloaded, propelling the selected car forward to push the empty car off the unloader and spot the next car in the train thereon and continuing the process until the selected car has reached the forward limit of its excursion, then selecting a similar intermediate car in the other train and repeating the process with it.

4. The-process of feeding cars to car unloaders and the like, which consists in providing a series of cars coupled in trains in parallel lines, then selecting an intermediate car in one train and propelling ittoward the unloader to push the cars in front and to pull the cars behind it until the leading car in the train is spotted on the unloader, then withdrawing the selected car to move the train back to clear the unloader, then after the spotted car has been unloaded propelling the selected car forward to push the empty car off the unloader and spot the next car in the train thereon and continuing the process until the selected car has reached the forward limit of its excursion, then selecting a similar intermediate car in the second train and repeating the process with it, then selecting a car in the remainder of the first train and carrying out the process as before.

5. The process of feeding cars to car unloaders and the like, which consists of providing a series of cars coupled in trains in parallel lines, then selecting an intermediate car in one train and propelling it toward the unloader to push the cars in front and to pull the cars behind it until the leading car in the train is spotted on the unloader, then withdrawing the selected car to move the train back to clear the unloader, then after the spotted car has been unloaded propelling the selected car forward to push the empty car off tion fco push until the next car ii s pbtite the unloade .azidapot the next car train thereon and eontinuingthe pfg H qxijsjil theselected car has reaehedthe foywai gili r ip of its, excursion, then selecting a simil at ipte me im car in h s nd: trai and; @Wi: g t pr s th; fihe ds lef in -a 9 in the remainder of the first t a in am anothex car in t he other train it-v about the;
